I would LOVE to rock a glide cam setup, especially when shooting live concerts. But is this feasible for on-the-go shooting? Moreover, is the glide cam setup okay for non-panning/gliding shots (relatively static)? Is it any less comfortable to shoot with than the other two mobile designs?

Not expecting a "perfect" solution as I realize all designs have their downsides. Given that, which of these is most feasible for this kind of shoot? Thanks in advance
